Prepare for rain when making Father's Day plans this weekend. ABC13 Meteorologist Travis Herzog said a surge of tropical moisture around a tropical wave now entering the Gulf will bring several rounds of rain starting Saturday and increasing through Monday. The National Hurricane Center is now only giving this tropical wave a 10 percent chance of developing into a tropical depression or storm over the weekend. Herzog said while the Gulf has a history of rapidly spinning up hurricanes, this is not one of those patterns. Any development would be slow to occur. Regardless of development, the wave will bring rough seas and a lot of tropical moisture into Texas this weekend. We are looking at three to four days with the potential for heavy tropical downpours that could flood streets. Travis says the most intense rains look to fall Sunday night through Monday, with 2-4 inches common but over 6 inches possible in isolated spots. Street flooding is most likely, but bayou and creek flooding cannot be ruled out. Some rain will be a welcome relief from budding drought conditions. Addicks and Barker reservoirs are empty and area bayous are low. Travis says we can handle several inches of rain if they come down at a manageable rate. Along the coast, expect deteriorating conditions through the weekend with minor coastal flooding, rough seas, and waves building up to 7 feet as winds increase to near gale force Sunday and Monday.
